Beschreibung
Zusammenfassung:	Disclosed are apparatuses and methods for non-contact processing a substrate, for example a glass substrate, overtop a gas layer. The support apparatus includes a plurality of gas bearings positioned on a pressure box supplied with a pressurized gas. Some embodiments are directed to a method of supporting and transporting softened glass. The method includes placing the glass in proximity to a gas bearing device having a support surface with a plurality of outlet ports disposed therein. Some embodiments are directed to a glass processing apparatus comprising an air table configured to continuously transport and support a stream of glass and a plurality of modular devices supported by a support structure and disposed above the air table. Some embodiments are directed to a method for flattening viscous glass using a two-sided gas bearing device or a one-sided gas bearing device.
